Flock - A web 2.0 browser

Have you heard of a
Flock browser? It is also called a Web 2.0 browser in some circles for its built-in support for the major web 2.0 features.
A screenshot of Flock (from Flickr): (You can see more screenshots
here) Flock is a mozilla/firefox based browser with custom, built in support for some of the better known "web 2.0" features such as easy and direct blog publishing for the most popular blogging tools, web bookmarks (del.icio.us) and integration with flickr. It also has a few very inovative features such as "recent" bookmarks and so called 'shelf' where you can drop some content for later. My first impression of the Flock was that it was a just a bigger Firefox with new skins and extensions. It was not a radical new experience as I expected. I am not trying to be harsh - that was really my first impression. At this point I am personally undecided on Flock. I am used to finding and installing some interesting Firefox extensions and I know Firefox extensions that can make Firefox do the same things as Flock. Regardless, I support Flock effort; I will keep it on eye and I wish them great success. More inovation in the browser space is good.
